Package: debian-installer Followup-For: Bug #740068 I do have same problem when suing today's (and last few days) netboot/mini.iso amd64 images. I was going crazy it is something with my machine memory, but normal memtest86+ is passing, including sequential tests on all cores. The memtest86+ parallel test fails always on 4th core, but I found it fails on few other machines, so this must be a bug in memtest86+ probably.
Anyway, It returns a segfault, usually during preparing libc6, but it sometimes happens at a different times. After that, the progress bar is stuck, and essentially every command in the shell fails. Maybe the libc6 was already unpacked and it affects all programs, or it is a kernel bug. Regards, Witek
